• Compatibility: designed for Lenovo devices using the Small Glass Synaptics assembly
• Form factor: compact PCB matching original module footprint and connector layout
• Components: includes touch controller circuitry and supporting passive components
• Mounting: intended for direct replacement within the device housing where the original module is installed

How to use

Power off the device and disconnect any batteries or power sources before beginning. Access the internal assembly following the device service manual or manufacturer disassembly guide to avoid damage. Remove the damaged sensor board by disconnecting the flex cable and any mounting fasteners; then install the replacement PCB glass sensor module by aligning the board to the original mounting points and reconnecting the flex cable and fasteners. Reassemble the device and reattach power, then perform a touch calibration or system test to verify restored functionality.

Recommendations

Handle the replacement module using appropriate electrostatic discharge (ESD) precautions and use correct torque for fasteners. Verify compatibility with the specific Lenovo model before installation and follow official service documentation for safe disassembly and reassembly. If touch functionality does not return after replacement, inspect connectors and cable routing for proper seating and check system software for required drivers or firmware updates.
